When many newcomers first enter this industry, they often do not understand the design process of PCB boards. Let us find out together:
Phase 1: Schematic Design
Engineers plan the basic modules of the circuit and draw the circuit diagram of the product according to the circuit site situation, market research or product innovation needs. This stage can be done without altium design software. Manuscripts and other office software generally meet the requirements. The following phases need to be applied to Altium Design software.
Phase 2: Schematic Design
Draw a specific schematic diagram according to the product circuit frame diagram to make the circuit system concrete. The design at this stage will determine the circuit structure and pcb board design wiring scale.
Phase 3: Export the component netlist information to the pcb board design
After drawing the schematic diagram, it is necessary to transfer the component package and component connection information to the PCB board design environment. The current advertising software can directly send the component netlist and component packaging information to the pcb board design environment with only one command, and has the functions of seamless docking and two-way synchronization.
Phase 4: Component Layout
After the component packaging is transferred to the pcb board design environment, the component layout needs to be carried out according to the product's chassis shape, panel structure, electromagnetic compatibility specifications, reasonable requirements for electrical layout, and pcb board design stack structure.
Phase 5: pcb board design and wiring
After the components are arranged, the pre-drawn lines generated according to the netlist in the pcb board design are filled with solid lines. This filling line is the copper foil line on the finished circuit board, and the rationality of the circuit board wiring will directly affect the quality of the circuit board.
Stage Six: Computer Aided Manufacturing Processing and Manufacturing
Electronic engineers are required to output GERBER files for processing and manufacturing.
